of rays be represented as it pours down at
noon on the day of summer solstice, the open-
ing day of the Egyptian year, we shall have
one face of the Pyramid of Light. Suppose
now that a quadrangular pyramid be erected
with four such sides facing respectively the
cardinal points of the heavens. Then since
each revolution of the earth is completed by
one quarter of a rotation later than the pre-
ceding, it follows that every fourth or grand
year the same face will be turned towards
the sun when the revolution of the earth is
accomplished; and thus the Egyptian Grand
Cycle (of four years) will be masonically ex-
pressed. Just such a form is found in the
quadrangular Pyramid of Light, its sides so
oriented as to have originally faced the
cardinal points, and its summit so truncated
as to permit the sun on one day in the
year to rest upon it " with all its rays,"
so that the building " devours its own
shadow."
